Traditional pressure testing equipment uses clamps to fix the pipelines, which cannot effectively fix pipelines of different diameters. During testing, errors will occur in the test values, resulting in poor reliability of the pressure testing equipment. Utility Model Content

[0031] Reference Figure 1-3 , a chemical pipeline pressure detection equipment, is used for the detection of chemical pipelines, in order to facilitate the detection of pipelines of different diameters and improve the reliability of detection.

[0032] The chemical pipeline pressure detection equipment includes a base 1, two sealing blocks 4, two sealing rings 5, a water pump and a support assembly;

[0033] A slide groove is provided on the base 1, and a slider is provided at the bottom of the movable seat 3. The slider can slide in the slide groove so that the movable seat 3 is slidably connected to the base 1. A pushing rod 2 is provided on the base 1, and one end of the pushing rod 2 is connected to the movable seat 3. The pushing rod 2 is an electric push rod, which can push the movable seat 3 to move on the base 1. One sealing block 4 is fixedly connected to the movable seat 3, and the other sealing block 4 is fixedly connected to the base 1. When the pushing rod 2 pushes the movable seat 3 to move, it will push the sealing block 4 on the movable seat 3 close to the sealing block 4 on the base 1, thereby clamping the pipe 6 between the two sealing blocks 4, fixing the pipe 6, and facilitating detection.

[0034] The two sealing rings 5 are respectively arranged on the outside of the two sealing blocks 4. The two sealing blocks 4 and the two sealing rings 5 are both conical. A plurality of stepped grooves 501 are provided on the outside of the two sealing rings 5. The stepped grooves 501 on the sealing rings 5 are arranged and distributed along the axial direction. The sealing block 4 moves so that the two ends of the pipe 6 are respectively embedded in the stepped grooves 501 corresponding to the two sealing rings 5. Since the diameters of the stepped grooves 501 are different, when clamping and fixing pipes 6 of different diameters, the ends of the pipes 6 can be embedded in the corresponding stepped grooves 501, thereby sealing the ends of the pipes 6, which is convenient for subsequent pressure testing of the interior of the pipe 6 by filling liquid.

[0035] An air outlet is provided on the sealing block 4 located on the movable seat 3, and a hose 14 is provided on one side of the air outlet. A float 13 is provided at one end of the hose 14. An air hole is provided on the float 13, and the air hole is connected to the hose 14. An air outlet pipe 16 is provided on the other side of the air outlet. A valve 15 and a pressure sensor are provided on the air outlet pipe 16. A water inlet hole 12 is provided on another sealing block 4, and a water inlet pipe 11 is provided on one side of the water inlet hole 12. One end of the water inlet pipe 11 is connected to the water outlet of the water pump, and a pressure sensor is provided on the water inlet pipe 11. The water pump is connected to the water inlet pipe 11, so that the water pump draws liquid, and the liquid enters the interior of the pipe 6 through the water inlet hole 12. The liquid enters the interior of the pipe 6, and the air inside the pipe 6 is discharged through the hose 14, the air outlet and the air outlet pipe 16 in turn. Since the float 13 has buoyancy, the float 13 can always float on the top of the liquid inside the pipe 6, so that when the liquid enters the pipe 6, the gas inside the pipe 6 is discharged, thereby facilitating the filling of liquid into the interior of the pipe 6 for pressure testing.

[0036] Each support assembly is used to support the pipe 6. Each support assembly is arranged and spaced along the axial direction of the pipe 6. Each support assembly includes a rotating rod 7, a lifting push rod 8, a rotating shaft 9 and two support wheels 10. The rotating rod 7 is rotatably connected to the base 1. The rotating shaft 9 is rotatably connected to the top of the rotating rod 7. The two support wheels 10 are rotatably connected to the two ends of the rotating shaft 9. The outside of the two support wheels 10 is provided with a rubber sleeve. The lifting push rod 8 is rotatably connected to the base 1, and the top of the lifting push rod 8 is rotatably connected to the middle of the rotating rod 7. The lifting push rod 8 is an electric push rod. The lifting push rod 8 can push the rotating rod 7 to rotate, thereby changing the support wheel 10, when supporting pipes 6 of different diameters, it is ensured that the axis of each pipe 6 coincides with the axis of the sealing ring 5, so that the sealing ring 5 can seal the end of the pipe 6 through the stepped groove 501, and the supporting wheel 10 facilitates the lateral movement of the pipe 6, thereby facilitating the movement of the sealing block 4. When clamping the pipe 6, the pipe 6 can move freely laterally, which facilitates the insertion of the conical sealing block 4 into the pipe 6 and clamping the pipe 6. In addition, each supporting component is provided with two supporting wheels 10, and the two supporting wheels 10 can support the bottom of the pipe 6 to improve the stability of the pipe 6.

[0037] The working principle of this chemical pipeline pressure detection equipment is as follows: first, the pipeline 6 is placed on each support assembly, and then the lifting push rod 8 drives the rotating rod 7 to rotate, thereby changing the height of the support wheel 10 so that the axis of the pipeline 6 and the axis of the sealing ring 5 are basically coincident. Then, the push rod 2 drives the movable seat 3 to move, thereby pushing the sealing block 4 on the movable seat 3 close to the sealing block 4 on the base 1, clamping the pipeline 6 between the two sealing blocks 4. During the clamping process, the end of the pipeline 6 can be embedded in the corresponding stepped groove 501, thereby sealing the end of the pipeline 6;

[0038] Then, liquid is pumped out through a water pump, so that the liquid enters the interior of the pipe 6 through the water inlet 12. After the liquid enters the interior of the pipe 6, the air inside the pipe 6 is discharged in sequence through the hose 14, the air outlet and the air outlet pipe 16. Since the float 13 has buoyancy, the float 13 can always float on the top of the liquid inside the pipe 6, so that when the liquid enters the pipe 6, the gas inside the pipe 6 is discharged until the interior of the pipe 6 is filled with liquid. At this time, the valve 15 on the air outlet pipe 16 is closed, and the pressure inside the pipe 6 is detected by the pressure sensors on the air outlet pipe 16 and the water inlet pipe 11 to observe whether the pipe 6 bursts within the preset pressure, thereby completing the pressure test.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
